Embodiment
As shown in the figure, Tail gas measuring sampling apparatus, comprises vapor box.Vapor box is provided with draft tube, draft tube is provided with valve body, be provided with piston in vapor box casing and vapor box case intracorporeal space is divided into two parts, vapor box is also provided with some escape pipes, escape pipe is provided with air outlet valve, draft tube and escape pipe are all communicated with one of them space in vapor box casing, the escape pipe of vapor box is connected with the air intake opening of pump bowl, piston is provided with in pump bowl, pump bowl is also provided with gas outlet, air intake opening on pump bowl and gas outlet are all positioned at the side of pump bowl inner carrier, air intake opening and gas outlet place are provided with valve body, gas outlet on pump bowl is connected with the air intake opening of gas tank A, the air intake opening of gas tank A is provided with gas admittance valve, gas tank A is communicated with by snorkel with gas tank B, piston is provided with in gas tank A, the side of piston is provided with pull bar, pull bar is arranged on the sidewall of gas tank A, sealing is provided with between the sidewall of pull bar and gas tank A, one end that pull bar is provided with holding tank is stretched in snorkel, above-below direction is respectively arranged with two pistons in gas tank B, each piston is all lived with pull bar and is connected, pull bar stretches out gas tank B and is connected with the bolt thread on gas tank B wall, gas tank B is also provided with exhausr port.
Described valve body is retaining valve.
Described gas admittance valve is retaining valve.
Described air outlet valve is retaining valve.
During use, motor exhaust enters in vapor box through gas admittance valve, and the escape pipe then through being connected with pump bowl air intake opening enters pump bowl, promotes the piston in pump bowl, gas enters gas tank A through pump bowl gas outlet, take out outside pull bar, the holding tank that pull bar is arranged enters in gas tank A, then promotes pull bar and enters snorkel, such tail gas sample enters gas tank B, turn pull bar push-and-pull piston, makes the tail gas in gas tank B be in pressure and the volume of requirement, is beneficial to detect it.Piston in vapor box, pump bowl, gas tank A, gas tank B is for adjusting the pressure of tail gas in certain space.
In order to make detection architecture more accurate, the pressure of tail gas sample and the accuracy requirement of volume also high, pressure can be set in vapor box, pump bowl, gas tank A, gas tank B and detect meter, and scale sign volume size is set on vapor box, pump bowl, gas tank A, gas tank B.
Namely gas on gas tank B can be used as sample for detecting.
Finally should be noted that: above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit; Although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the field have been to be understood that: still can modify to embodiment of the present utility model or carry out equivalent replacement to portion of techniques feature; And not departing from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technical scheme scope of the utility model request protection.
